Wiring harness fixing device and automobile

Abstract

The invention discloses a wiring harness fixing device. The wiring harness fixing device comprises a base and a binding tape, wherein a fixed hole fixed together with a fixed foundation is formed in one side of the base; the fixed hole can be matched with a thread tightening piece; the other side of the base is a binding tape connecting side; and a wiring harness supporting surface and a through hole which is for the binding tape to pass through are formed on the binding tape connecting side. In the wiring harness fixing device, as the fixed hole is formed in the base and the fixed hole is matched with the thread tightening piece, the whole wiring harness fixing device can be fixed through the thread tightening piece. Obviously, a gap is not prone to appear between the wiring harness fixing device and the fixed foundation; therefore, the wiring harness fixing device is not prone to generate shaking due to the vibration of an automobile during running. In addition, as the gap is not prone to appear between the wiring harness fixing device and the fixed foundation, the position of the wiring harness fixing device relative to the fixed foundation is guaranteed so as to guarantee that the position of a wiring harness is not prone to change; therefore, the reliability in fixing the wiring harness is high. The invention further discloses an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to a wire harness fixing device. The invention also relates to a motor vehicle. Background technique [0002] There are a large number of wiring harnesses in automobiles, and the layout environments of these wiring harnesses are relatively diverse. With the continuous improvement of the reliability requirements of electrical systems, the fixing methods of wiring harnesses also need to be differentiated according to different requirements to meet their reliability requirements. [0003] Such as figure 1 As shown, the wire harness fixing device in the conventional technology includes a buckle 11 and a cable tie 12 fixedly connected with the buckle 11. The buckle 11 includes a pressing foot 111, a buckle body 112 and a buckle foot 113, and the three are fixedly connected. The pressing foot 111 is pressed on one side surface of the fixed base (such as a sheet metal part)...

AI Technical Summary

Problems solved by technology

[0004] However, due to the large vibration when the car is running, and in order to ensure the installation convenience of the buckle 11, the pressing foot 111 itself has a certain degree of flexibility. Under the above-mentioned vibration, the pressure between the pressing foot 111 and the fixed foundation will become smaller, causing a gap between the two, causing the harness fixture to vibrate relative to the fixed foundation

In addition, in the aforementioned vibration environment, once there is a gap between the pressing foot 111 and the fixed foundation, it will cause the buckle body 112 to rotate relative to the fixed foundation, and finally drive the wire harness to rotate, causing the position of the wire harness to change. Therefore, the fixing of the wire harness poor reliability
